Proof step 6 from proof is_obj-addobj-01 (previous step)

fis .keys = instfields(class), validfieldinits(fis, st), class+∃(str, class) ⊦ r = jvmref, is_abstract(class), is_obj(str, r, addobj(r, class, fis, st))

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ is_obj(str, r, st) ↔ class+∃(str, st[r -- _type] .type .class) ∧ ¬ is_abstract(st[r -- _type] .type .class) ∧ is_obj(r, st)
Proof step 5:
fis .keys = instfields(class), validfieldinits(fis, st), class+∃(str, class) ⊦ r = jvmref, is_abstract(class), class+∃(str, (addobj(r, class, fis, st)[r -- _type]) .type .class) ∧ ¬ is_abstract((addobj(r, class, fis, st)[r -- _type]) .type .class) ∧ is_obj(r, addobj(r, class, fis, st))

Rule argument

[crewrite-arg: is-real-object-def , F , [st, r, str] → [addobj(r, class, fis, st), r, str] ]
